“Microsoft has been hard at work bringing the best of Sunrise calendar into Outlook,” a Microsoft representative told me. “Today that motion is especially important because it’s also the day that Sunrise officially shuts down. But not to worry. The Sunrise you know and love isn’t going away. It is Microsoft’s goal to bring email and calendar into one seamless experience, and today marks an important milestone in that mission – two teams joining forces and putting all their creative energy into one powerful app to help you manage your work and personal life no matter the device you’re on.”

“One last note to let you know that we’re moving on for good to Outlook and shutting down the Sunrise apps on iOS, Android, Mac and web,” the post notes. “This is definitely the end of an era. But more importantly, it’s the beginning of a new one. We’re excited by what’s ahead and we’d love for you to come and join us in our latest adventure. We’ve kept our promise to bring the magic of Sunrise to the Outlook calendar – and the Outlook inbox while we were at it – and we’re only getting started.”

So here’s the schedule.

Starting today, Sunrise will stop updating your calendars, and any changes you make in the app will not be made to the underlying service(s). Likewise, any changes you make to the calendars will not be reflected in Sunrise. Starting tomorrow, Sunrise users will be logged out of the app. (Naturally, Microsoft reminds users that “all the information held in your calendar will still be available on the original platform you were using (Gmail, iCloud, Outlook, etc.).”)
